SER, IR, DAR -- Irregular verb's past form
Hi everyone
I'm so confused by the past form of Ser, Ir, Dar
in the expaination "Dar"'s past form should be: doy, damos, das, dais, da, dan.....
but when it come to sentences it became: le di el boleto, me dierom el boleto......
it feel like it is following the regullar change of er verb, why?

and also in explaination ser and ir should be: soy, somos, eres....... voy, vamos, vas......
but in sentences it seems like ser and ir should change to fu.. and it follow the regular er changings (i, imos, iste, isteis, io, ieron)
like : fui al campo por autobus
but there are two places gos like: fue una fiesta fantastica / paralee fue a machupichu para ver las llamas
why it is fue here? or why shouldn't it be fuio?

thank you so much
I'm really confusing here

Answer

I think it will be clearer to you this way

SER
 
  Present

(yo) soy
(tú) eres
(él) es
(nosotros) somos
(vosotros) sois
(ellos) son

Past

(yo) fui
(tú) fuiste
(él) fue
(nosotros) fuimos
(vosotros) fuisteis
(ellos) fueron

DAR

Present

(yo) doy
(tú) das
(él) da
(nosotros) damos
(vosotros) dais
(ellos) dan

Past

(yo) di
(tú) diste
(él) dio
(nosotros) dimos
(vosotros) disteis
(ellos) dieron

IR

Present

(yo) voy
(tú) vas
(él) va
(nosotros) vamos
(vosotros) vais
(ellos) van

Past

(yo) fui
(tú) fuiste
(él) fue
(nosotros) fuimos
(vosotros) fuisteis
(ellos) fueron

" (Yo)Le dí el boleto..."  I gave the ticket   -   "Me dieron el boleto (Ellos a mi)"... They gave me the ticket 
"Yo fui al campo" (verbo IR) ...I went to field...
"Esta fue una fiesta..(verbo SER)....It was a party....

ATTENTION: The past form of verbs SER and IR are equals, they are written in the same way!!!!

Yo fui al campo (verbo IR)   Yo fui un actor (verbo SER)
TU fuiste a la fietsa (verbo IR)  Tu fuiste mi amigo (verbo SER)

Answer

Hi!
There's no explanation. "Ser", "ir" and "dar" are irregular verbs and you have to learn it by heart. But you're wrong with "dar"'s past tense:

Presente: doy, das, da, damos, dais, dan.
Pretérito perfecto simple: di, diste, dio, dimos, disteis, dieron.

And "ser" and "ir" are identical in this past tense and also irregular:
Pretérito perfecto simple: fui, fuiste, fue, fuimos, fuisteis, fueron
